Kilroy J. Oldster said this quote
“ Self-mastery involves a studious account of all aspects of human life and developing a comprehensive philosophy for living without fear or anxiety throughout the remaining years of a person’s life. A person must live within the limits of the human condition, which does not justify giving into all of our destructive impulses or living a pleasurable and guiltless life. Self-mastery does not require a person to live a life without passion; rather, it entails channeling vibrant personal passions into living in a virtuous manner of created beings. ”
